t is the time from the start of the test in minutes, and T is the mean furnace temperature in °C. Further details relating to the practical application of this curve, and other test parameters, e.g. tolerances, are given in EN 1363-1. 5 Resistance to fire performance characteristics 5.1 Performance characteristics 5.1.1 Introduction 5.1.2 to 5.1.4 describe which performance characteristics apply to which products/elements. 5.1.2 E – Integrity Integrity E is the ability of a component of a service installation to prevent the transmission of fire as a result of the passage of significant quantities of flames or hot gases from the fire to the unexposed side, thereby causing ignition either of the non-fire exposed surface or of any material adjacent to that surface. The assessment of integrity is made on the basis of one or more of the following aspects simultaneously:  cracks or openings in excess of given dimensions;  ignition of a cotton pad;  sustained flaming on the unexposed side;  leakage in excess of given values. The integrity shall be determined by all methods during the test. The cotton pad procedure shall be applied until the pad ignites and, once it has ignited, it shall be withdrawn and the test continued until all aspects have been exceeded (the sponsor has the option, however, of stopping the test once the desired level has been reached). The times of each mode of integrity failure shall be recorded. Classification of integrity is according to whether or not the component is also classified for insulation. Where a component is classified both for integrity E and insulation I, the integrity value shall be that determined by whichever of the four criteria fails first. Where a component is classified E but without an I classification, failure of the cotton pad shall not be taken into account. When testing fire dampers or fire resisting ducts against the slow heating curve (EN 1363-2), the leakage criteria are applicable. However the leakage rates measured during the first 25 min of the test shall be disregarded. For dampers, cracks or openings, ignition of cotton pad and sustained flaming on the unexposed side shall be taken into account only for the area around the duct and wall or floor junction. The criterion inside the duct containing the damper shall be the limitation of the leakage rate to 360 m3/(m2⋅h) after the first five minutes of exposure to the standard temperature/time curve.
